Decided to go with 400W SE 10K EVC bulbs. According to Sanjays analysis they pull down 204 PAR. That is compared to the 250W AB bulbs I have now at 104 par, or the phoenix bulbs at 88 par.
My wife said - "Buy the 10k for growth now, then in september get the 14k bulbs for color for reef tour". I think I caught her in a really good mood today...
Kull - the bulbs I just bought are the 250W DE/HQI Phoenix 14k's. (Really good color out of these bulbs. And quite bright, also)
Adam - I have no idea. I think I caught her in a good mood. Hence the need to act quickly...
